Question 35863
{{{ln (1/x) = 2}}}


First, raise both sides as a power of e, to undo the ln.

{{{e^(ln (1/x)) = e^2}}}
{{{1/x = e^2}}}  or {{{1/x = (e^2)/1}}}


There are several ways to do the next step.  I like to invert both sides of the equation.  In other words, if two quantities are equal, then their reciprocals are also equal.  Flip both sides:

{{{x/1 = 1/(e^2)}}}  or {{{x = e^-2}}}


Unfortunately, I left my calculator at the office today, so you'll have to do the calculation yourself.
